I'm happy to take on the position of editor in chief of IJMO. It's a journal that shows promise of becoming a recognized journal in the area of modelling and optimization. I'll work together with the editors to help it progress.

Modeling of Spectrum Demands through Hybrids of Analytic Hierarchy Process and Integer Programming

Abstract—As wireless technology advances, demand for
spectrum bandwidth increases and thus, spectrum has become
scarce. As a scarce resource, spectrum bandwidths need to be
efficiently allocated to potential service providers. Hence, this
paper first reviews current approaches on how spectrum
bandwidths are being allocated to the service providers. Then
we present an efficient integrated approach in allocating
spectrum volumes, whereby the approaches of Analytic
Hierarchy Process and Integer Programming are integrated
and applied to produce systematic and consistent allocation
results. The integrated approach is able to cater multi-criteria
problems through determination of suitable weights and
computations, which exhibits a more efficient alternative as
compared to the existing approaches. The illustrations revealed
that the integrated approach indeed has the potential to be
implemented and gives an alternative to the current existing
approaches.
